I'm on the autism spectrum, and I sometimes have issues controlling my tone of voice as well as volume. Sometimes I'm like a tiny squeaky mouse, but another day I'M THE LOUDEST PERSON ON CAMPUS. I'm just completely unaware of my volume most of the time, and my tone of voice might be completely wrong, because I mix up what is appropriate for what social interaction. However, Solamnicknight, I can relate to you, as I get anxiety easily. Sometimes my own actions scare me. And when someone gets mad at me or raises their voice suddenly, I go into an anxiety filled spiral. It makes me very scared, I suppose? In general, I'm nowadays able to tell people when I get a little scared of them or don't understand what they mean, but there's still folk that I'm too scared to confront.

This probably wasn't advice, but I just want you to know you're not alone.
